The Zenith Martlet fight is arguably the hardest fight in Undertale Yellow.
The fight forces you to be at Lv 19, giving you 94 HP, and at this point in the game, you have access to things such as the Wild Revolver (Multiplies damage output by 6) and Friendliness Pellets (+11 Attack), and the Golden Bandana (+12 Defense).
This fight has none of that.
0 Attack.
0 Defense.
I am also set to Lv 17. The yellow soul mode (at least in Phase 1), for some reason, relies on your attack stat, meaning that the lower your Lv, the less damage your soul does to Martlet. (Note the amount of damage my soul does in Phase 1)
Lv 17 is the lowest Lv that still does damage (any lower and the damage is rounded to 0).
With a lowered attack and defense, as well as 0 stat boosts, this was the toughest (and longest) Zenith Martlet fight.
